168. When a number is in parenthesis, you just multiply, so multiply the 3 times the 56 to get 168.
Answer:
Slope: -5
y-Intercept: -1
Step-by-step explanation:
In the equation y = mx + b (its the form of a linear equation) the slope is m and the y-intercept is b. Comparing that to the problem, we can see that m = -5 and b = -1. So, the slope is -5 and the y-intercept is -1.
So, what we have to do is split 10000
0.04(2500) + 0.05(7500)
Multiply:
100 + 375 = 475
$475 is made in one year
Step-by-step explanation:
y is directly proportional to x
y = kx
k represents the constant of proportionality.
when y = 20 and x = 8:
20 = 8k
Dividing both sides by 8 gives:
k = 2.5
Hence when x = 3.
y = 2.5(3)
y = 7.5 .
